Before Delporte's work, there was no standard list of the boundaries of each constellation. Delporte drew the boundaries along vertical and horizontal lines of right ascension and declination ; however, he did so for the epoch B1875.0 , which means that due to precession of the equinoxes, the borders on a modern star map (e.g., for epoch J2000 ...
